Study Notes

Importance of Aseptic Technique

Aims to prevent contamination during medication administration
Sterile equipment is essential, including syringes and needles
Proper hand hygiene and gloving are key to minimizing contamination risk
Safe disposal of sharps prevents needlestick injuries

Importance of Needle Removal Technique

Needle should be removed at the same angle used for insertion
Prevents tissue trauma and discomfort
Avoids complications like bleeding or hematoma formation
Consistency in technique is vital for patient safety and comfort

Overview of Injection Types

Intradermal (ID): Administered into the dermis, used for TB and allergy tests
Subcutaneous (Subcut): Given into the adipose tissue, suitable for insulin administration
Intramuscular (IM): Administered in larger muscles like the ventrogluteal or deltoid, used for vaccines

Intradermal Injection Considerations

Longest absorption time among parenteral routes due to fewer blood vessels
Requires careful landmarking to ensure accurate placement

Subcutaneous Injection Considerations

Administered into the adipose tissue layer beneath the dermis
Allows for slow and steady absorption
Common sites include the outer upper arm, abdomen and thighs

Intramuscular Injection Considerations

Administered in larger muscles, like the ventrogluteal or deltoid
Ensure proper needle depth for effective delivery into muscle tissue
Requires careful site selection to prevent injury to nerves or vessels

Guidelines for Preventing Medication Errors

Avoid distractions during medication preparation: create “No-interruption zones”
Use two patient identifiers: Two forms of identification to confirm patient identity
Perform patient assessments: To ensure the right medication at the correct time
Double-check medication calculations: To avoid dosage errors

Medications for Injection

Ampules: Small glass containers that hold liquid medication
Vials: Single or multi-dose containers, often with a rubber seal
Prefilled syringes: Pre-measured dosages, reduce needlestick injuries and dosing errors### Aseptic Technique
Crucial for parenteral medication administration to prevent infection
Injections bypass the skin's protective barrier, increasing risk of infection
Pathogen introduction can lead to complications:
- Localized infections
- Systemic infections
- Sepsis
Aseptic Technique Procedures:
- Sterile equipment (syringes, needles)
- Proper skin cleaning before injection
Benefits:
- Protects patient
- Improves efficacy of medication
- Promotes safety and professionalism in healthcare settings

Parenteral Medication Routes

Intradermal:
- Slow absorption
- Used for:
  - Allergy testing
  - Tuberculosis screening
Subcutaneous:
- Steady absorption rate
- Often used for:
  - Insulin
  - Heparin
- Suitable for self-administration
Intramuscular:
- Rapid absorption
- Penetrates deeper into muscle tissue
- Larger volumes can be administered
- Used for:
  - Vaccines
  - Certain medications requiring rapid absorption
Intravenous:
- Delivers medication directly into bloodstream
- Immediate effects
- Precise drug level control
- Used for:
  - Emergency situations
  - Situations requiring rapid action

Patient Education

Essential for:
- Compliance
- Overall health outcomes
Benefits:
- Fosters patient ownership and responsibility
- Increases likelihood of following treatment plans
- Alleviates anxiety
- Improves patient experience
Allows for:
- Patient questions and concerns to be addressed

Anatomical Landmark Selection

Crucial for:
- Medication effectiveness
- Minimizing complications
Each injection type has specific optimal sites
Improper site selection can lead to:
- Inadequate medication absorption
- Increased pain
- Complications such as hematomas or abscesses
Proper Rotation:
- Repeated injections in the same area can cause tissue damage and scarring

Medication Errors

Consequences:
- Adverse drug reactions
- Ineffective treatment
- Increased healthcare costs
Error Prevention Strategies:
- Standardized medication preparation and administration protocols
- Technology like barcode scanning
- Culture of Safety:
  - Encourage reporting near misses and errors
Ongoing education and training on evidence-based practices for healthcare providers
Regular audits and feedback mechanisms for improvement

Vulnerable Populations

Ethical considerations when administering parenteral medications to:
- Children
- Elderly
Informed Consent:
- Difficult to obtain from children or cognitively impaired elderly patients
- Involve guardians or family members
- Prioritize patient best interests
Increased Sensitivity:
- Careful assessment of risks versus benefits
- Dosage and administration techniques require adjustments
Patient Comfort and Dignity:
- Techniques to minimize pain and anxiety
Patient-Centered Approach:
- Respect autonomy
- Promote safety
- Ensure equitable access to care
